An improvement has been needed for some time.
I wonder though if there was any local consultation before the plans were signed off.
It seems to me a much more sensible way would have been to incorporate a slip lane for traffic coming from Warooka heading north.
I would refer to the intersection south of Ardrossan where the Yorke Highway joins the St Vincent Highway via a slip lane, which works extremely well.
The problem with the plan for Butler Road intersection is vehicles, particularly large trucks, et cetera, approaching from the south, will be faced with a sudden decline and a veer to the right with the need to pull up abruptly at a give way or stop sign.
This will make the intersection much more dangerous than it already is.
Common sense would suggest a slip lane to continue towards Minlaton would make for a much smoother and safer progression!
Indeed, the addition of a merging slip lane to the existing roadway is really all that is needed and could have been done years ago at a minimal cost.
